Hi nice to meet you all I'm a nooby here and I would like to know if someone knows much about this watch? It not marked with a manufacturer as such however it had ds&s on the inside of the clasp, with platinum clearly stamped. The watch has diamonds around the outer side of the face, with blue diamonds on the face. I don't really know much about this watch as it was my late grandmothers. I have tried to remove the back casing however it does seem to want to come off and I'm frighted of damaging it. Would anyone know the history of this watch?
